Tunable Mediated Interactions Near Spontaneous Symmetry Breaking: From Yukawa to Coulomb and Dzyaloshinskii--Moriya Interactions
Hoshu Hiyane, Hiroyuki Tajima
We propose a realization of tunable long-range mediated interactions generated by Nambu-Goldstone (NG) modes near spontaneous symmetry breaking. An effective exchange interaction e…
Condensate-mediated dimerization of impurities in atomic BECs
Hoshu Hiyane, Thomás Fogarty, Jose Carlos Pelayo +1
We show that strongly correlated impurities confined in an optical lattice can form localized, molecule-like dimer states in the presence of a Bose-Einstein condensate (BEC). By sy…
Bose-Fermi -polaron state emergence from correlation-mediated blocking of phase separation
Felipe Gómez-Lozada, Hoshu Hiyane, Thomas Busch +1
We study fermionic impurities in a one-dimensional lattice bosonic bath at unit filling. Using DMRG and mixed boundary conditions-periodic for bosons, open for fermions -- we f…
Emergence of nonequilibrium Lieb excitations in periodically driven strongly interacting bosons
Hoshu Hiyane, Giedrius Žlabys, Thomas Busch +1
We study the exact nonequilibrium spectral function of a gas of strongly correlated Tonks-Girardeau bosons subjected to a strong periodic drive. Utilizing the theory of Floquet spe…
Imaging Josephson Vortices on Curved Junctions
Yuita Fujisawa, Anjana Krishnadas, Barnaby R. M. Smith +5
Understanding the nature of vortices in type-II superconductors is crucial for comprehending exotic superconductors and advancing the application of superconducting materials in fu…
The Lieb excitations and topological flat mode of spectral function of Tonks-Girardeau gas in Kronig-Penney potential
Wen-Bin He, Giedrius Žlabys, Hoshu Hiyane +2
Lieb excitations are fundamental to the understanding of the low energy behaviour of many-body quantum gases. Here we study the spectral function of a Tonks-Girardeau gas in a fini…
